MODULAR CEILING SYSTEM
[0001]
FIELD OF THE INVENTION
[0002] This invention relates to a modular ceiling system, and more
particularly to a modular
ceiling system that accommodates a plurality of uniformly appearing devices
that are integrated
into a single control network.
BACKGROUND OF THE INVENTION
[0003] A typical prior art ceiling in a commercial building offers a platform
for the installation
of numerous devices including for example, room lights, emergency lights,
cameras, speakers,
sensors, Wifi access points (WAP), cell phone repeaters, sprinkler heads, drop-
down signage,
and HVAC grills. The sensors may include for example, light sensors,
temperature sensors,
smoke sensors, and occupancy/motion sensors.
[0004] The devices are often supplied from multiple sources and attached to
multiple control
systems. Consequently, the devices often are incompatible with each other and
with other
device control systems. Particularly, the devices may have different
communication protocols
and may not communicate with each other or with other control systems. The
resulting prior art
ceiling may include a redundancy of devices and infrastructure. Further, the
prior art ceiling
has poor flexibility thereby making upgrades difficult. Such a prior art
ceiling with multiple
incompatible devices require careful coordination between trades during design
and installation
resulting in additional time and cost. As a result, the aesthetic appearance
of the prior art
ceiling represents a hodgepodge of incompatible, non-uniform devices and a
hodgepodge of
multiple control systems.
[0005] Particularly, a typical prior art ceiling presents two distinct
problems. First, the prior art
ceiling is aesthetically unappealing because the devices are not uniform in
appearance, and the
installation of openings in the ceiling are not uniform in shape, size, and
trim. While architects
spend time addressing the aesthetic appearance of a building interior, the
appearance of the
ceiling is compromised when the contracting teams and consultants install
numerous ceiling

devices, none of which match in look or color. Second, the prior art ceiling
lacks interoperation
integration between and among devices and control systems.
SUMMARY OF THE INVENTION
[0006] The present invention addresses the problem associated with the prior
art ceiling. The
modular ceiling system of the present invention includes a range of devices
similar in
appearance. The devices may be installed in channels or frames that are
designed to work with
ceilings constructed of sheetrock, wood, metal, and others, materials.
Alternatively, the devices
may be surface mounted on a ceiling of any type. Further, the devices may be
flush mounted
on the ceiling.
[0007] When devices are installed in a channel, the system includes ceiling
support structure
that supports the channel which in turn supports an array of ceiling panels
and the various
devices, including without limitation, room lights, emergency lights, cameras,
speakers,
sensors, Wifi access points, cell phone repeaters, sprinkler heads, access
tray, and HVAC grills.
The access tray may accommodate overhead signage, a video screen, a Wi-Fl
access point, or
other electronic equipment. The channel is recessed in the ceiling so that the
bottom edges of
the channel are flush with the surrounding ceiling panels. Alternatively, the
channel may be
surface mounted and extending below the plane of the ceiling panels. The
channel has
uniformly sized and shaped openings that are arranged in an aesthetically
pleasing pattern in
coordination with the individual ceiling patterns or in an array of ceiling
panels. Each of the
openings in the channel is sized and shaped to accommodate one of the devices.
Each of the
devices includes a housing that is uniformly sized and shaped to fit into the
uniformly sized and
shaped openings in the channel. The housings of the devices are mounted in the
openings of
the channel so that the housings are either flush with the surrounding ceiling
panels or are
recessed within the channel from the surrounding ceiling panels. All of the
housings for the
devices are designed to have essentially the same shape, size, and color. Each
individual device
is contained within a separate case. Each case is sized and shaped to fit
within the housings.
Because the cases and housings are of the same size and shape, casings can be
swapped
between and among the housings thus allowing for easy reconfiguration of the
devices in the
ceiling. In addition, trim around each of uniformly sized and shaped openings
also has a
uniform shape, size, and color. Further, the channel of the modular ceiling
system of the
2
CA 03053955 2019-08-19
WO 2018/157234
PCT/CA2018/000044
present invention accommodates conduits and the associated wiring for the
distribution of
power and data, piping for sprinkler heads, and ducts for HVAC grills.
[0008] Alternatively, the uniformly sized and shaped housings for the devices
can be directly
surface mounted on the ceiling panels without the use of the channel. When
surface mounted,
the uniformly sized and shaped devices are arranged in a pleasing geometry on
the ceiling
panels. Again, because the cases and housings are of the same size and shape,
casings can be
swapped between and among the housings thus allowing for easy reconfiguration
of the devices
on the ceiling.
[0009] A further alternative contemplates flush mounting the uniformly sized
and shaped
housings for the devices in the ceiling panels without the use of the channel.
When flush
mounted, the housings are mainly concealed above the ceiling panels with only
the face of the
devices visible to the room below.
[0010] Integration or interoperation of the devices is achieved by installing
ceiling devices that
have a common communication protocol so that a single building management
system (BMS)
network can manage all of the devices. A common communication protocol and
single building
management network will save on installation time, commissioning, and possibly
in fewer
devices overall. The network will add functionality to key devices, eliminate
the need for two
networks which are typical in construction (lighting and BMS), as well as
simplify how devices
communicate both with the building management system and with each other and
how the
devices are commissioned. The network and low voltage DC power are combined in
the same
category five (CAT5) cable to greatly reduce wiring and installation cost and
complexity.
[0011] Further objects, features and advantages will become apparent upon
consideration of the
following detailed description of the invention when taken in conjunction with
the drawings and
the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0090] With reference to Figs. 1-7 and 13-14, a modular ceiling system 10
includes a ceiling
support structure 12 (Figs. 6 and 7) that supports rails 54 extend along a
length of the ceiling.
The rails 54 in turn support ceiling panels 14 by means of flanges 56. The
rails 54 also support
a channel 24 extending along a length of the ceiling. The channel 24 has a
series of uniformly
sized and shaped openings 30 (Fig. 5) in which uniformly sized and shaped
devices 36 are
fitted. The uniformly sized and shaped devices 36 include uniformly sized and
shaped housings
38 that are fitted into the openings 30. The housings 38 support uniformly
sized and shaped
cases 40 for each of the devices 36. With reference to the Fig. 1 such devices
36 include for
example emergency lighting 102, strobe light 104, environmental sensors 106,
smoke detector
108, broadcast sprinkler 110, concealed sprinkler 112, speaker 114, security
camera 116, and
panoramic camera 118.
[0091] Because the openings 30 in the channel 24 are uniformly sized and
shaped, the housings
38 of the devices 36 are necessarily uniformly sized and shaped for
accommodation in the
openings 30. Each of the openings 30 may have trim on the room side 26 of the
channel 24. In
order to assure uniformity of appearance, the trim for each of the uniformly
sized and shaped
openings 30 is likewise uniform in size, shape, and appearance.
[0092] With continued reference to Figs. 1-7, the ceiling panels 14 have a
front, room side 16
and a back side 18 (Figs. 6 and 7). The channel 24 has a planar front side 26
(Fig. 1) and a
planar back side 28 (Fig. 4). The plane of the front side 26 of the channel 24
may be recessed
from the plane of the front side 16 of the ceiling panels 14 as shown in Figs.
1 2, 3, 6, 7, and
13B-13D. Alternatively, the channel 24 may be surface mounted on the ceiling
so that the
plane of the front side 26 of the channel 24 is flush with the plane of the
front side 16 of the
CA 03053955 2019-08-19
WO 2018/157234
PCT/CA2018/000044
ceiling panels 14 as illustrated in Fig. 4 and 14B-14D. In a further
alternative, the housings 38
for the devices 36 may be flush or semi-flush mounted in openings 30 in the
channel 24.
[0093] In addition to the uniformly sized and shaped openings 30 with uniform
sized and
shaped housings 38, the channel 24 also has a tray opening 42 that
accommodates a drop-down
tray 44. The drop-down tray 44 serves several purposes including a location
for access to
functional components of the modular ceiling system, a video monitor, or
lighted signage. Fig.
1 shows the drop-down tray 44 in the extended position, and Fig. 5 shows the
drop-down tray in
the retracted position. In addition, the channel 24 has an liVAC opening to
accommodate an
HVAC grill 50 (Fig. 2) extending along a portion of the length of the channel
24. The HVAC
unit 72 (Fig. 5) is supported by the channel 24 and delivers conditioned air
to the HVAC grill
50 fitted into an opening in the channel 24.
[0094] Fig. 5 shows the details of the back side 28 of channel 24. The
backside 28 of the
channel 24 provides support for cables, piping, and ducts. Particularly, the
backside 28 of the
channel 24 has a set of rails 54 running lengthwise along opposite sides of
the channel 24. The
rails 54 include flanges 56 on either side that support the ceiling panels 14.
In addition, the rails
54 have a series of support clips 58 extending along the length of the rails
54. In one
embodiment, the support clips 58 support four wire conduits including life and
safety conduit
62, high voltage conduit 66, low voltage conduit 64, and backup/expansion
conduit 60. The life
and safety conduit 62 houses the wiring for smoke and fire detectors,
sprinkler control, and
emergency lighting. The separate life and safety conduit 62 ensures that
emergency systems
operate in the absence of power and control signals unrelated to emergencies.
The high voltage
conduit houses the power cables for ordinary lighting, distributed HVAC units,
electric service
outlets, and distributed network control modules. The low voltage conduit 64
houses wiring for
communication with the devices and wiring for other communications, such as
telephone and
computer wiring. The backup/expansion conduit 60 provides housing for wiring
that may be
required for future enhancements of the modular ceiling system 10 and for
replacement wires if
one or more wires in the other conduits fail.
[0095] A sprinkler system supply pipe 68 is shown in Figs. 5 and 7. The supply
pipe 68 is
connected to sprinkler head 112. When activated, the concealed sprinkler head
unit 512
extends from the housing 38 as illustrated in Fig. 7.

D show the
channel 24 flush mounted with respect to the plane of the front surface 16 of
the ceiling panels
14, and Figs. 14F-D show the channel surface mounted and protruding below the
plane of the
front surface 16 of the ceiling panels 14. Particularly, Figs. 13A-D show a
series of channel
mounted devices 36 ¨ emergency light 102, strobe 104, environmental sensor
106, smoke
detector 108, broadcast sprinkler 110, concealed sprinkler 112, speaker 114,
camera 116, and
panoramic camera 118. Figs. 13A-B show the appearance of each of the devices
102-118 from
the room side. As can be seen in Figs. 13B-D, the channel 24 is flush mounted
so that the
channel 24 does not protrude below the plane of the front surface 16 of the
ceiling panels 14.
Likewise, the individual devices 102-118 do not protrude substantially from
the channel 24
below the plane of the front surface 16 of the ceiling panels 14. Fig. 13C
shows the aesthetic
appearance of the channel mounted devices 36 from the room side with the
devices 36 in the
channel 24 flush with the plane of the front surface 16 of the ceiling panels
14.
[0097] Figs. 14A-D show a series of channel mounted devices 36¨ emergency
light 102, strobe
104, environmental sensor 106, smoke detector 108, broadcast sprinkler 110,
concealed
sprinkler 112, speaker 114, camera 116, and panoramic camera 118. Figs. 14A-B
show the
appearance of each of the devices 102-118 from the room side. As can be seen
in Figs. 13B-D,
the channel 24 is surface mounted so that the channel 24 protrudes below the
plane of the front
surface 16 of the ceiling panels 14. The individual devices 102-118, however,
do not protrude
substantially from the channel 24 as shown in Fig 14B. Fig. 14C shows the
aesthetic
appearance of the channel mounted devices 36 from the room side with the
devices 36 in the
channel 24. The channel 24 is surface mounted, and the channel 24 protrudes
below the plane
of the front surface 16 of the ceiling panels 14.
[0098] Alternatively, the channel 24 can be eliminated and housings 38 can be
mounted
directly to the ceiling, either flush mounted or surface mounted. Figs. 8A-E,
9A-D, and 11A-F
show the devices 36 flush mounted with the front room side surface 16 of the
ceiling panels 14
or drywall. With reference to Fig. 8A, the housing 38 is inserted into an
opening 30 in the
ceiling panel 14. The housing 38 has fixing clips 86 that engage the backside
18 of the ceiling
panel 14 such that the room side end 39 of the housing 38 is flush with the
room side 16 of
ceiling panel 14 as best seen in Fig. 8E. When the housing 38 is secured in
the opening 30 of
the ceiling panel 14, the case 40 is inserted into the housing 38 and secured
by bayonet
12
CA 03053955 2019-08-19
WO 2018/157234
PCT/CA2018/000044
connectors 84. As will be discussed in greater detail, the casing 40 is
standardized to
accommodate each of the devices 102-118. The housing 38 in Fig. 8A-E further
has a
mounting flange 88 attached to the room side end 39 of the housing 38. The
mounting flange
88 distributes load over an area of the room side surface 16 of the ceiling
panel 14. Once the

[0112] Fig. 24 shows a typical prior art ceiling system configuration with a
first network and
control system 74 for managing the lights for a building space and a second
separate network
and control system 76 for managing the environment and occupancy of the
building space. In
such a prior art ceiling configuration, the network and control systems 74 and
76 are separate
and do not have interoperability between them.
[0113] Figs. 25 shows an example of the modular ceiling system 10 in which a
single device
network 78 controls the lights 96 and the environment for a room (for example,
environmental
sensors 106, smoke detector 108, HVAC unit 72, window shade 94, and emergency
lighting
102). The network 78 has control line 80 that is connected to a central
building management
system (not shown). In addition, the network 78 is powered by a low-voltage
line 82. All of
the devices are connected to the control line 80 and are managed by a single
network protocol
from the central building management system. In addition, the
driver/controller/user interface
modules 98 are micro controllers that allow the user interface, the
controllers, and the drivers to
communicate directly with each other independently from the building
management system 70.

[0114] Fig. 26 illustrates the various devices for the modular ceiling system
10. The modular
ceiling system 10 provides a substantial number of advantages including for
example,
simplifying the exchanging of physically and electrically compatible devices,
flexibility for
reconfiguration when room layout changes occur, generating localized
atmospheres within a
room, allowing retrofitting for future technology, reducing time and cost of
installation,
reducing backroom infrastructure, reducing installation costs based on
reducing the number of
trades involved in the ceiling installation, and providing a minimalist and
coordinated
appearance.
[0115] Fig. 27 illustrates shows a device network 79 for a modular ceiling
system 10. The
device network 79 has a control line 80, a security line 81, and a fire line
83. The control line
80 interconnects for example environmental sensors 106, lighting 96, HVAC
units 72, interface
modules 98, window shade 94, emergency lighting 102, and smoke detector/fire
notifier 108.
Security cameras 116 are interconnected by security line 81. In addition, the
smoke
detector/fire notifier 108 is also connected to fire line 83. As previously
indicated, each of the
devices has the ability to communicate with every other interconnected device.
As shown in
Fig. 27, the devices share the same wiring and network. Zones are defined by
software and can
be created, deleted, and merged as occupancy requirements change for the
building. Software
configuration is done by way of a computer (not shown) plugged into the USB
port of any wall
interface modules 98. Devices communicate with devices in their software zone
on an ad-hoc
basis, rather than through a centralized system.
[0116] While this invention has been described with reference to preferred
embodiments
thereof, it is to be understood that variations and modifications can be
affected within the spirit
and scope of the invention as described herein and as described in the
appended claims.
